A Worcester man arrested Thursday night in a drainage tunnel was accused of trying to break into his ex-girlfriend's house while armed with a pair of scissors, according to police.

Massachusetts State Police said the man was yelling outside the woman's home in Worcester, holding what appeared to be a knife, when police were called. He ran when police arrived, hopping a fence and running into the woods near Williamsburg Drive.

State police, with the help of a K-9, Nanuk, eventually found the man in an aqueduct tunnel. The dog found the man hiding in a small opening leading up to a manhole cover, police said.

Afterward, police said they found text messages from the man to his girlfriend, saying he would kill her if she didn't let him in.

Miguel Rolon, 53, was arrested and charged with a number of crimes, including breaking and entering, assault with a dangerous weapon and resisting arrest. He was expected to be arraigned on Friday.
